2021 FDA Endocrinology Approvals: Novel Small Molecules Deep Dive

together with Dr. Jennifer Huen, Saumil Patel, and Dr. Naveed Yasin In 2021, the FDA approved 9 non-radiological novel small molecule drugs for oncology. Excluding melphalan flufenamide, which has already been withdrawn, the remaining FDA-approved novel small molecule oncology drugs of 2021 are: umbralisib (PI3Kδ and CK1ε inhibitor) sotorasib [...]

PI3 kinases are part of the PI3K/Akt/mTOR signaling pathway that is downstream of Receptor Tyrosine Kinases (RTKs), G-protein-coupled receptors (GPCR), and GTPases such as KRAS. Since their identification in the 1980s, and due to their central role in cancer, the therapeutic targeting of the phosphatidylinositol-3-kinase (PI3K), and more [...]

KIN-3248 (Kinnate Biopharma) is a next-generation, irreversible, pan-fibroblast growth factor receptor inhibitor (FGFRi) in a first-in-human (FIH) dose-escalation study (NCT05242822) in adults with advanced tumors harboring FGFR2 and FGFR3 gene alterations. The program is an excellent case study for rational covalent drug design to address kinase mutations while maintaining sufficient PK properties for oral daily dosing in humans.
